Philosophical debates on the nature and significance of values in scientific knowledge and practices have differentiated cognitive (or epistemic) values from noncognitive (non-epistemic, such as moral or political) ones. The significance of cognitive values has come to be more or less commonly accepted, but the place of noncognitive values is much more controversial. Analysis and debate on values-related dimensions of scientific knowledge and inquiry has been on the rise in contemporary philosophy of science since 1970. This chapter provides an overview (...) of some current philosophical work on the subject and its possible impact on school science education. -/- First, a sample of these philosophical stances is presented, with emphasis on three different authors who recognise the role of non-epistemic values in scientific activity, without necessarily relinquishing a place for objectivity. Then, some of the rationales for including teaching about values in science education are addressed. The science education and philosophy education research is deployed to sketch some issues that would have to be taken into consideration when introducing one particular type of values – ethics related issues – in the secondary education classroom. -/- Finally, the desirability of a greater interaction among science and philosophy educators is emphasised. Mutual knowledge of the convergences and divergences in approach to values in scientific knowledge and practices, and the challenges posed by teaching about them, can lead to richer and more nuanced approaches to the common aspects in their respective topics.
